What do the LED colours on the HovalConnect gateway mean?
The HovalConnect gateway is a white box measuring approximately 10x10 cm, which you can use to connect your Hoval system to the internet.
The gateway can be connected to the internet using a LAN cable or the WLAN antenna, depending on your configuration.
Your gateway has 3 LED indicators
